>> - When is subdivision performed?
The subdivision is done at the end of parsing. And the new subdivided
mesh is kept in memory and ray-traced. Clearly this isn't the optimal
method,
due the memory reason, and the fact that pressing stop won't stop
the parsing process. On-the-fly method would have the advantages,
and again a nice thing to implement next. It will likely kill the
export_mesh option, though.

It discards the new traingles that are on the boundary.
Take a look at figure 3 in the following paper by Bischoff etc.

This is useful in some occasions, for example what I did in my euro-graphics
2004 paper
(visualizing the loop patches.)
